From a970a9764c773ae6daa94db934dfe3d790bfc977 Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Wed, 25 Nov 2020 03:46:54 +0000 Subject: sparc: Fix handling of page table constructor failure The page has just been allocated, so its refcount is 1. free_unref_page() is for use on pages which have a zero refcount. Use __free_page() like the other implementations of pte_alloc_one().
